My father's love of teaching and in particular imparting his knowledge of gardening had unforeseen consequences. I was about four years old when my mother took a phone call from our elderly neighbour. "Do you know what Rachel is up to?" she asked my mother. "She's in the garden playing," my mother replied. With a strangled hoot of laughter, the neighbour suggested that my mother might want to investigate what I was actually doing and where.

My mother found me in the middle of my father's vegetable patch, covered in mud and dragging an overfilled watering can around; huffing and puffing with exertion on a hot summer's day as I tried to water some newly-dug holes. There was a carefully drilled row studded with bright, fresh tomatoes and nestling under a large rhubarb plant, a box of eggs. Sitting under the shade of the apple tree, my baby brother watched solemnly, surrounded by several unidentified tins, a package of cheese, a slab of bacon and a bottle of milk. I had dragooned the poor boy into helping me carry the contents of the kitchen fridge out into the garden.

To muffled giggles wafting over next door's hedge, my mother asked me: "Rachel, what are you doing?" "Well," I replied carefully, "we are planting things." "Yes, I can see that, but why?" "To make more," came the logical reply.

We don't throw away as many tomatoes in the UK as we once did – it is down from 2m tomatoes thrown away every day in 2007, to a mere 1.5m in 2012. But that is 45,000 tonnes of tomatoes wasted at home every year. Apparently we throw them away because we think they have gone off; we just don't use them up in time. 32,000 tonnes of tomatoes are thrown away every year because they are considered too ripe.

I think part of the problem may be that often we buy tomatoes that are slightly under ripe. We set them aside and then they reach the point that they are too soft. Tomatoes should be firm and plump with a lovely aromatic smell. While most advice about keeping your tomatoes fresher for longer is by storing them in the fridge, I don't because I think it subdues the flavour and destroys the texture - although there is nothing wrong with freezing them if you are planning to cook them in a sauce or stew.

I store my tomatoes in a brown paper bag and leave them on a sunny windowsill. I am convinced that they taste better this way; certainly fresh raw tomatoes taste much better at room temperature.

Heat 2 tablespoons of oil in a saucepan over a medium to low heat. Add the shallots, garlic, chillies and galangal (or ginger, if using). Gently fry, stirring occasionally, until the shallots have softened and are a light golden brown (but no darker). This may take about 10 minutes.

Tip in the beans and tomato. Stir well to combine. Fry for 2 to 3 minutes.

Add the coconut milk, water, palm sugar, salt and trassi powder, if using. Stir well to combine. Bring to a gentle boil and then simmer for 15 to 20 minutes, stirring occasionally. Keep on a low heat as you don't want the coconut milk to split or curdle. The beans should be soft but not mushy.

Check the seasoning and adjust if necessary. Remove the galangal (or ginger) before serving. Leave to cool a little before eating – there is much more flavour.There will be a fair amount of liquid, which I like to mop up with naan bread.

This is a great way of adding a little extra flavour to your salad dressings or to stir into soup. The tomatoes have a sweetness which marries really well with vinegar.

You will need to work out how much vinegar you will need by putting your tomatoes in a screw-top jar and pouring in enough water to fill the jar. Pour the water into a measuring jug to work out how much vinegar you will need. I needed 200ml.

Pour the appropriate amount of vinegar into a stainless steel saucepan. Add the sugar, bay leaf, garlic and peppercorns. Bring to the boil and then simmer until the sugar has dissolved. Remove from the heat and set aside.

Put the tomatoes in a sterilised screw-top jar. Pour over the vinegar together with the bay leaf, garlic and peppercorns. Leave to cool before sealing. Leave in a cool place for about 2 weeks to allow the flavours to develop.

Use the vinegar in your favourite salad dressings, drizzle over soups or to add a hint of acidity to stews or marinades.

Tip:Make an insertion in the tomatoes with a sharp knife, and then squash the tomatoes slightly. If you can give the jar a shake every few days it will chivvy things along. Strain the vinegar into a clean jar or bottle. I add the remaining pulp to salad dressings and stews for more tart flavours.

Other recipe ideas with tomatoes:

4. There is a children's joke about how you can tell whether there has been an elephant in your fridge. By the footprints in the butter, in case you are interested. Well, you could always tell when my late father had made himself at home by the trail of crumbs and bits of tomato. He had no shame and would quite happily potter about in someone else's kitchen foraging for bread or crackers and tomatoes. A grinding of pepper and a little olive oil to top it all off. Cheese would be lovely too, but possibly a case of gilding the lily. So famous was my father for this simple pleasure that we thought he had invented tomatoes-on-toast!

5. Continuing the theme of tomatoes with bread, the Italian bread salad, panzanella is definitely worth a try too. It is the perfect picnic salad, full of Mediterranean flavours.

6. Cod "Marie Chiaro" is a sunny Mediterranean-influenced recipe from Food52 that cooks fish with a few tomatoes with black olives, capers, fresh basil and oregano.
